I´ll try Is xbmc able to switch between 50/60 Hz depending if it´s pal/ntsc with one fixed modeline? - dannybullit - 2009-05-20 boba23 Wrote:Eh? I have no clue where you got that info from? Thanks for the lession Basically I should be ok with the default xorg.cong that comes with 9.04?! Perhaps I need to add Option "DynamicTwinView" "False" I´ll start a new thread for my issue with getting only 1080i instead of 1080p /D - User 29008 - 2009-05-20 dannybullit Wrote:I´ll try Actually it should it switches between 50hz PAL and 24p for me just fine. Can't tell about 60hz since I don't have native NTSC material here .... boba - dannybullit - 2009-05-20 boba23 Wrote:Actually it should it switches between 50hz PAL and 24p for me just fine.

So this is my tested and verified combination what works without issues for me: I´ve got 1080p! But using your modeline the output won´t fit the screen. Is it the displaysize I should adjust? Br, Daniel - cejstrup - 2009-05-21 glad to hear that There is a bit of overscan yes. Just adjust the screen inside xbmc,this is what I do. Works fine. - dannybullit - 2009-05-23 cejstrup Wrote:glad to hear that I will try to get 1080p without using a modeline, I don´t want the overscan. Do you know which edid options I can use to achieve this, without using a modeline? using the default xorg.conf, xbmc can switch between 24 and 50/60 Hz, this does not work when using modeline. Br, Daniel - cejstrup - 2009-05-24 No idea. As I said before if I use EDID my TV doesn't report 1080p capability because the EDID isn't properly updated/or linux doesn't read it correctly. I don't think you can avoid overscan to be honest. And it doesn't matter ,just fine tune inside XBMC takes a couple of seconds and you're good to go I only run the 60Hz modeline and I can play 24p and 50Hz content without problems.No stutter.Smooth playback That's why I haven't bothered to try to make a 50Hz modeline (my TV can't do 24p). - soder - 2009-05-26 boba23 Wrote:Eh? I have no clue where you got that info from? But if native 24 fps would suck, how do you get XBMC to play 24 fps-movies in 48 fps or 72 fps? I can choose the Hz I've in my nvidia settings, OR I can choose to have XBMC to change the Hz to the fps the movie use? /Söder - User 29008 - 2009-05-26 soder Wrote:But if native 24 fps would suck, how do you get XBMC to play 24 fps-movies in 48 fps or 72 fps? AFAIK players, e.g. BluRay or here XBMC would ouput 24p as 24hz signal to the TV set, and then, as mentioned above, a TV Set with 24p support (Pulldown etc.) converts the signal to 48 or 72hz. It's not XBMC that is supposed to do that conversion. boba - soder - 2009-05-26 boba23 Wrote:AFAIK players, e.g. BluRay or here XBMC would ouput 24p as 24hz signal to the TV set, and then, as mentioned above, a TV Set with 24p support (Pulldown etc.) converts the signal to 48 or 72hz. It's not XBMC that is supposed to do that conversion. Ok. So that should be done automatic if the TV get 24 hz via HDMI? My TV can only show 50 Hz or 60 Hz in 720p, and 24 Hz, 50 Hz or 60 Hz in 1080p. It says it support real 24p and I guess that is what 2:2 and 3:3 pulldows is. But I guess I first have to edit my xorg to be able to change between 24, 50 and 60 in the nvidia setting, and then change XBMC to change the rate after the movie? But will the 2:2 or 3:3 pullback automic happen if the signal is 24 Hz. How do I know if the TV display the native 24p or not? Or shall I maybe change the settings in nvidia to be able to handle 72 hz instead? /Söder - User 29008 - 2009-05-26 Quote:But I guess I first have to edit my xorg to be able to change between 24, 50 and 60 in the nvidia setting, and then change XBMC to change the rate after the movie? Well it depends on your installation/distro maybe ... for me with a kinda clean Ubuntu 9.04 with latest Nvidia driver installed, I do NOT have to add any modelines to my xorg.conf. It just works out of the box. I have auto refresh rate on in XBMC, and XBMC adjusts the refresh rates depending on the movie source on the fly using "xrandr". Pressing "Z" during playback shows me 24hz output for 24p material, and 50hz output for PAL SD material .... that's what I want. Quote:How do I know if the TV display the native 24p or not? Depends on your TV I'd say, my Panasonic Plasma only shows me 1080p, 720p etc. but not the refresh rate .... I'd say though if your TV can't handle 24p you would see it, e.g. stuttering during playback. boba - soder - 2009-05-26 boba23 Wrote:Well it depends on your installation/distro maybe ... for me with a kinda clean Ubuntu 9.04 with latest Nvidia driver installed, I do NOT have to add any modelines to my xorg.conf.

Im running it in 720p, but I wanna try 1080p to be able to try 24p. BUT I have not good modelines that works, so now Im stucked with 720p in 60 Hz. Or 50 Hz. /Söder - dlmh - 2009-05-26 cejstrup Wrote:Yes,I guess you should be able to.I don't know that application so I can't tell you for sure.Finally got to it, here's the displaymodes according to the manual, hope you can help me!
